Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playards have complex folding mechanisms that are difficult for users to operate, resulting in poor user experience and low folding efficiency.
Innovation Solution
A one-button foldable bed frame design featuring a connecting rod assembly connected to the bottom frame rod and a sliding member slidably connected to the upright rod, allowing for easy unfolding and folding by rotating the bottom frame rod to drive the sliding member and frame-around connecting rods to specific positions, simplifying the operation and enhancing folding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms are used on each side of the upper bumper, then the bed frame can be securely locked, but the operation process becomes complicated and difficult for users to perform
Solution Approach 1:
The patent combines multiple locking mechanisms into a single integrated locking device that simultaneously locks all four sides of the upper bumper. This merging of functions allows one locking operation to secure the entire bed frame, resolving the contradiction between secure locking and ease of operation.
Solution Approach 2:
The locking device is designed with multi-functionality, serving both as a secure locking mechanism and as a user-friendly interface. The single-button design provides universal ease of operation while maintaining the reliability of secure locking through the integrated mechanism that engages all four sides simultaneously.
2Reliability
If multiple separate locking operations are required for base and bumper, then secure locking is achieved, but the operation process becomes time-consuming and reduces folding efficiency
Solution Approach 1:
The locking device is pre-configured to simultaneously engage all four sides of the upper bumper when activated. This preliminary arrangement of the locking mechanism ensures that secure locking of all components is achieved in a single operation, eliminating the need for multiple sequential locking steps and thereby improving folding efficiency.
Solution Approach 2:
The patent merges the locking operations for the base and all four bumpers into a single integrated action. The locking device simultaneously secures all components, achieving both reliable locking and high folding efficiency by eliminating sequential operations.
3Stability of the object's composition
If complex folding mechanisms are used to ensure stability, then the bed frame remains stable, but the structure becomes complicated and difficult to operate
Solution Approach 1:
The bed frame is divided into modular segments (base, upright rods, bumpers) that can independently fold while maintaining overall stability. This segmentation allows each component to be simplified in design while the coordinated folding of all segments preserves the stability of the complete structure.
Solution Approach 2:
The folding mechanism incorporates dynamic elements that automatically maintain stability during the folding process. The mechanism transitions smoothly between folded and unfolded states, providing stability at each stage without requiring complex static structures, thereby reducing overall device complexity.
